Sets the amount of time that all dynamic OTP page selection pins must be stable before the device responds to a level change on any dynamic OTP page selection pin. Once all active dynamic OTP page selection pins have been stable for the selected amount of time, the resulting OTP Page Selection Code is registered and the selected page is loaded into the device registers. Any dynamic OTP page selection pin level changes that occur between the expiration of the debounce interval and completion of OTP autoload will be ignored until OTP autoload finishes. If the registered OTP Page Selection Code matches the current OTP Page Selection Code (for example, a short pulse was observed on the pin) or if the registered OTP Page Selection Code is invalid, no OTP autoload will occur. 0x0 = 133ns 0x1 = 4.2us

Bit	Field	Type	Reset	Description
7	I2C_REG_ADDR_FMT	R/W	0x0	I2C Register Address Format. Selects between 1-Byte Addressing and 2-Byte Addressing. In 1-Byte Addressing, only one byte of register address (the lower 8 bits) must be transmitted. The upper 2 bits are controlled by the PAGE_SEL_x register fields. In 2-Byte Addressing, two bytes of register address (all 10 bits) must be transmitted. The PAGE_SEL_x register fields are ignored. The required value of this field should be loaded from OTP. 0x0 = 1-Byte Addressing; The upper 2 bits of the register address must be written to the PAGE_SEL field. 0x1 = 2-Byte Addressing; The PAGE_SEL field is not used. Instead, all ten register bits are acces through two subsequent 8-bit I2C accesses.
6:0	I2C_TRGT_ADDR	R/W	0x6C	I2C target address 7 bits, does not include R/W bit. This field is locked, and requires unlocking UNLOCK_PROTECTED_REG before using.

R8 is shown in Table 3-10.

Return to the Summary Table.

Table 3-10 R8 Register Field Descriptions

Bit	Field	Type	Reset	Description
7:0	PWRGD_SAMPLE_TMR	R/W	0x0	PWRGD Function Sampling Timer. The value of this field sets the earliest time that the GPIO pin assigned with the PWRGD/PWRDN# function will be sampled for use with the PWRGD function. This timer exists to ensure that the pin is not sampled before it is stable. This timer starts once the voltages of both VDDA and VDDD reach 1.62V. When the timer expires, the value of the pin starts being evaluated for use with the PWRGD function. If PWRGD is asserted before the timer expires, the PWRGD function is seen to be asserted upon timer expiration. If PWRGD is asserted after the timer expires, the PWRGD function is seen to be asserted as the pin value changes. The timer is enabled/disabled using PWRGD_SAMPLE_TMR_EN. The timer is ignored if no pin is assigned with the PWRGD/PWRDN# function (for that case, see SUP_LVL_RAMP_TMR and GLOABL_SUP_DET_TMR). The timer duration, which can range from 0.1ms to 25.6ms, is configured using the following equation: PWRGD_SAMPLE_TMR = 10 * timer_duration (ms) - 1

3.9 R9 Register (Offset = 0x9) [Reset = 0x12]

R9 is shown in Table 3-11.

Return to the Summary Table.

Table 3-11 R9 Register Field Descriptions

Bit	Field	Type	Reset	Description
7	RESERVED	R	0x0	Reserved
6:1	SUP_LVL_RAMP_TMR	R/W	0x9	Supply Level Ramp-up Timer. The value of this field controls the duration of the Supply Level Ramp-up Timer. For each power supply pin (VDDA, VDDD, VDDX, VDDR, VDDO_, VDD_REF), a timer exists to ensure that the device does not begin operation until the power supply pin has ramped up to its final voltage. For each pin, this timer starts once the pin voltage reaches 1.62V. When the timer expires, the device assumes that the power supply is fully ramped up, and supply detection for that pin no longer gates device operation. The user must set this field according to the longest expected power supply ramp-up time, measured from 1.62V to the final voltage. This timer is ignored if a GPIO pin is assigned with the PWRGD/PWRDN# function (for that case, see PWRGD_SAMPLE_TMR). The timer duration, which can range from 0.1ms to 6.4ms, is configured using the following equation: SUP_LVL_RAMP_TMR = 10 timer_duration (ms) - 1
0	PWRGD_SAMPLE_TMR_EN	R/W	0x0	PWRGD Function Sampling Timer Enable. When set to 0x1, the PWRGD Functrion Sampling Timer is used to delay sampling of the GPIO pin assigned with the PWRGD/PWRDN# function. See PWRGD_SAMPLE_TMR for further details. When set to 0x0, timer is not used, and the pin begins getting sampled immediately after pin functions are loaded from the OTP.

3.10 R10 Register (Offset = 0xA) [Reset = 0x00]

R10 is shown in Table 3-12.

Return to the Summary Table.

Table 3-12 R10 Register Field Descriptions

Bit	Field	Type	Reset	Description
7:0	GLOBAL_SUP_DET_TMR	R/W	0x0	Global Supply Detect Timer. The value of this field controls the duration of the Global Supply Detect Timer. This timer exists to ensure that if one of the supply detect pins (VDDA, VDDD, VDDX, VDDR, VDDO_, VDD_REF) fails to ramp up, the device will not hang. This timer starts once the voltages of both VDDA and VDDD reach 1.62V. Once all power supply pins that are expected to be used (FLOAT_VDDx == 0x0) reach 1.62V and their corresponding Supply Level Ramp-Up Timer expires, the device will begin all remaining power-up sequence steps and clocks will start. If this timer expires before that condition occurs, the device will stop waiting for power supply pins to ramp up, and the device will begin all remaining power-up sequence steps. While this prevents the device from hanging, it may result in unintended behavior. The user must set this field according to the longest allowable delay between core power supplies starting to ramp up, and the first output clocks starting. The timer is enabled/disabled using GLOBAL_SUP_DET_TMR_EN. This timer is ignored a GPIO pin is assigned with the PWRGD/PWRDN# function (for that case, see PWRGD_SAMPLE_TMR). The timer duration, which can range from 0.1ms to 25.6ms, is configured using the following equation: GLOBAL_SUP_DET_TMR = 10 timer_duration (ms) - 1

3.11 R11 Register (Offset = 0xB) [Reset = 0x30]

R11 is shown in Table 3-13.

Return to the Summary Table.

Table 3-13 R11 Register Field Descriptions

Bit	Field	Type	Reset	Description
7	FOD0_PD	R/W	0x0	FOD0 Power-Down. Setting this bit to 1 turns off power to FOD0. This can be used to reduce power consumption in configurations where FOD0 is not used. 0x0 = Powered Up; FOD0 is not powered down. 0x1 = Powered Down; If FOD0 is not needed (pure buffer mode operation), then FOD0 is powered down for current savings. In general, FOD0 should be used for clock generation from the BAW resonator if only one FOD is needed.
6	BAW_PD	R/W	0x0	BAW Power-Down. Setting this bit to 1 turns off power to the BAW. This can be used to reduce power consumption in configurations where the BAW is not used. 0x0 = Powered Up; The internal BAW resonator is not powered down. 0x1 = Powered Down; If the internal BAW resonator is not needed (pure buffer mode operation), then the BAW is powered down for current savings when setting this field to a 1. When powering off the BAW, both FODs should also be powered off.
5	AUTO_FOD_PD_EN	R/W	0x1	Automatic FOD Power-down Enable. When enabled, if an FOD is not selected as the source of any output clock or reference clock, that FOD will be automatically powered down. If an 0x0 = No; If an FOD is not used for any outputs, it will still be powered up (increasing current consumption and potentially FOD-FOD crosstalk) 0x1 = Yes; If an FOD is not used for any outputs, it will still be automatically powered down (reducing current consumption and potentially FOD-FOD crosstalk)
4	CRC_IGNORE	R/W	0x1	CRC Ignore. When set to 0x1 (default), if a CRC error is detected during OTP autoload, the CRC_ERROR status bit will be set, but the device will attempt to continue to power up normally with the loaded OTP data. When set to 0x0, if a CRC error is detected, the CRC_ERROR status bit will be set, and the device power-up sequence will stop. In this case, no output clocks will be generated. 0x0 = Halt; If there is a CRC error (CRC_ERROR set to 1), the device will halt the startup process. No output clocks will be generated. 0x1 = Ignore; If there is a CRC error (CRC_ERROR set to 1), it will be ignored, and the device will attempt to start up normally.
3	PIN_RESAMPLE_DIS	R/W	0x0	Pin Resample Disable. By default, when the device exits power-down mode (the PWRDN# pin is deasserted or the PDN register field is written to 0x0), GPIO0, GPIO1, and GPIO2 are sampled. Each sampled value is used for OTP Page Selection (Power-Up) if the corresponding OTP_PAGE_SEL_PU_x register field is configured to use the GPIO pin. If this field has a value of 0x1 while exiting power-down mode, this pin re-sampling will not occur, and the last sampled values of the GPIO pins will be retained.
2	OTP_AUTOLOAD_DIS	R/W	0x0	OTP Autoload Disable. By default, when the device exits power-down mode (the PWRDN# pin is deasserted or the PDN register field is written to 0x0), OTP data is loaded into the device registers; however, if OTP_AUTOLOAD_DIS has a value of 0x1 while exiting power-down mode, this data transfer will not occur. The OTP_AUTOLOAD_DIS register field has no effect on dynamic OTP page changes. When changing the device settings and doing a PDN toggle to recalibrate the FODs, this field should be written to a 1 before PDN is cleared to prevent reloading from OTP.
1	PDN	R/W	0x0	Power-Down. Writing this bit with 0x1, which is equivalent to asserting the PWRDN# pin, causes the device to enter a power-down mode. Writing this bit with 0x0, which is equivalent to deasserting the PWRDN# pin, casuse the device to exit power-down mode. The resulting behavior from entering/exiting power-down mode is defined by the PIN_RESAMPLE_DIS and OTP_AUTOLOAD_DIS register fields. When modifying the FOD divider values, TI recommends setting PDN to 1, setting OTP_AUTOLOAD_DIS to 1, then setting PDN to 0 to recalibrate the FODs for best performance.
0	GLOBAL_SUP_DET_TMR_EN	R/W	0x0	Global Supply Detect Timer Enable. When set to 0x1, the Global Supply Detect Timer is used to prevent the device from hanging if one of the power supply pins is slow to ramp up. See GLOBAL_SUP_DET_TMR for further details. When set to 0x0, timer is not used, and if a supply pin is slow to ramp up, the device will hang until it finishes ramping up.

3	IN2_PD	R/W	0x0	IN2 Power-Down. Setting this bit to 1 turns off power to IN2. This can be used to reduce power consumption in configurations where IN2 is not used. 0x0 = Powered Up; IN_2 is not powered down. 0x1 = Powered Down; Setting this field to a 1 reduces power consumption in configurations where IN_2 is not used.
2	IN1_PD	R/W	0x1	IN1 Power-Down. Setting this bit to 1 turns off power to IN1. This can be used to reduce power consumption in configurations where IN1 is not used. 0x0 = Powered Up; IN_1 is not powered down. 0x1 = Powered Down; Setting this field to a 1 reduces power consumption in configurations where IN_1 is not used.
1	IN0_PD	R/W	0x0	IN0 Power-Down. Setting this bit to 1 turns off power to IN0. This can be used to reduce power consumption in configurations where IN0 is not used. 0x0 = Powered Up; IN_0 is not powered down. 0x1 = Powered Down; Setting this field to a 1 reduces power consumption in configurations where IN_0 is not used.
0	FOD1_PD	R/W	0x1	FOD1 Power-Down. Setting this bit to 1 turns off power to FOD1. This can be used to reduce power consumption in configurations where FOD1 is not used. 0x0 = Powered Up; FOD1 is not powered down. 0x1 = Powered Down; If FOD1 is not needed (pure buffer mode operation), then FOD1 is powered down for current savings. In general, FOD0 should be used for clock generation from the BAW resonator if only one FOD is needed.
